Question

Cells A and B are the same size, shape, and temperature, but cell A is metabolically less active than cell B; cell B is actively converting oxygen to water in cellular respiration. Oxygen will diffuse more rapidly into cell __________ because __________.

A. A; its membrane transport proteins will not be saturated
B. A; the concentration gradient there is shallower
C. B; the diffusion gradient in cell B is steeper
D. B; the oxygen molecules inside cell B have a higher kinetic energy
E. B; the gradient of oxygen is oriented in the opposite direction compared to cell A

Answer 1

Answer:

The correct answer is: C) B; the diffusion gradient in cell B is steeper.

Explanation:

Size, shape and temperature don't matter, because the level of metabolic activity that cell B presents by actively converting oxygen to water in cellular respiration, produces a more pronounced diffusion gradient that will ultimately lead to the faster diffuse of oxygen into this cell.
